"This pretty much took us by surprise, so we are talking about adding more shows. I apologise if you didn't get seats. We're working on it," Idle tweeted. The Monty Python veteran said that he will be directing the stage production.

Last week, the surviving members of Monty Python held a press conference in London to announce their reunion. The last time the group performed together was in 1998 at the U.S. Comedy Arts Festival in Colorado.

The group's surviving members include Idle, John Cleese, Terry Gilliam, Terry Jones and Michael Palin. (The sixth Python member, Graham Chapman, died in 1989.)

Monty Python's reunion production is expected to consist of a mix of new and existing material. It remains unclear if the group will take the show to the U.S. On a Reddit session last week, Cleese indicated that they may "possibly" take the show to New York.

They are all officially senior citizens -- and so are many of their fans -- but that isn't stopping the surviving members of Monty Python from planning a reunion that is expected to take the form of a stage show.
